Fig. 1. Nitophyllum divaricatum. A portion of a large fertile plant. The base is shown near the right-hand margin of the figure, and the lobing of the blades is characteristic. The dark edge and distinct light sterile border are very easily distinguished from the dark granular central region where the tetrasporic sori are located. I. Santa Cruz. x 0.6.
Fig. 2. Hemineura Howellii. A portion of a fertile plant. The base is shown toward the lower left-hand corner of the figure. The midribs are clearly shown in the foliar segments, which in the older parts (upper left) are crisped but in the younger ones (right-hand side) are plane. The fertile branchlets are shown in various stages, with the sterile midrib evident in some. I. Santa Maria. x 1.1. [= syn. of Austrofolium howellii (W.R.Taylor) M.J.Wynne, AlgaeBase]
